Creating a SIP profile

To create a SIP profile for VoIP use, the following SIP settings are needed:

Id of the SIP settings (APPID)

ID for the VoIP settings.

Default: w9010.

Profile name (PROVIDER-ID)

A name to describe the settings and identify this particular set of parameters. Using the same name as for the VoIP profile settings is recommended.

Service profile type (PTYPE)

Service profile type indicating the supported SIP dialect. The only possible value for Asha Java VoIP API v1.0 VoIP Settings is IETF.

Public user name (PUID)

A SIP URI for the user including the hostname part, that is, the SIP domain name provided by the service provider. For example, sip:[email protected] or sip:[email protected].

Value may be given without a sip: or sips: prefix, in which case sip: is automatically added.

Transport type (APROTOCOL)

UDP — UDP transport forced to be used.
TCP — TCP transport forced to be used.

If this parameter is not defined the transport is selected according to RFC 3261, that is, UDP is used for initial requests <1300 bytes long and TCP for initial requests >1300 bytes long.
Default: UDP.

Note:

If this parameter is present and Proxy server address (ADDR) is not presented as an IPv4/6 address and Proxy server parameter PORTNBR is not defined, then NAPTR queries are skipped and only SRV and A or AAAA record lookups are made (see IETF RFC 3263 for more information).

Signaling QoS (SIGQOS)

Quality of Service for signalling, the DiffServ Code Point (Differentiated Services, DSCP bits) QoS values to be used in IP headers (IPv4 TOS and IPv6 TC).

A number in range of 0 to 63.
Default value: 40.

Timer T1 (TIMER-T1)

SIP timer T1, the RTT estimate. This is an estimate for the round trip time in the system (between the phone and proxy). See RFC 3261 for reference.

A timer value in milliseconds in the range of 500 to 5000.
If this parameter is not defined, the default value of 800 ms is used.
Default: Parameter is not defined.

Timer T2 (TIMER-T2)

SIP timer T2, the maximum retransmit interval for non-INVITE requests and INVITE responses. See RFC 3261 for reference.

A timer value in milliseconds in the range 1000 to 40000.
If this parameter is not defined, the default value of 6400 ms is used.
Default: Parameter is not defined.
